The Gilbert Bridge in the Philippines.

Crack repairs on the Gilbert bridge in the Philippines with Roadware 10 Minute Concrete Mender.

Roadware 10 Minute Concrete Mender is great repairing surface cracks in a bridge deck. The flow-and-go application along with the 10 minute cure time allow repair crews to get on and off the bridge quickly. Traffic can be returned to the bridge in just 10 minutes after application. In the Philippines, crews often work at night when traffic is low and working conditions are cooler.

Crews work in teams. One person shoots the Concrete Mender from 600ml cartridges, one person applies filler sand, and one person trowels the repair smooth.

What are the reasons DOT’s Roadware?

1) “Safety for the driving public.” Roadware repairs are ready for traffic in 10 minutes. Lane closure time is dramatically reduced.

2) “Safety for my crew.” The interstate is a dangerous work environment, the quicker repairs are made, the less exposure to the hazards of working on a heavily traveled interstate.

3) “Saves a lot of money.” Quick cure times, easy mixing, straight forward application, and good long term performance makes Roadware 10 Minute Concrete Mender a good value. After a few days of training, the crew was able to repair a bridge in half a day. One district in Wisconsin saved about $1500 per bridge over conventional repair methods. No overnight lane closures are needed and crews are more productive with less equipment requirements.

For many years, engineers have looked for ways to fully inject repair polymers into cracked concrete structures. The general consensus is to seal off the crack with a sacrificial epoxy and install injection ports every few inches. Then thick epoxy is injected under high pressure into the crack with expensive resin injection pumps. The process is time-consuming, the epoxy is brittle, the equipment is expensive and the skill level is highly specialized. This makes epoxy injection slow, expensive and not really effective in the field.

At Roadware, we look for ways to make concrete repair fast, effective and easy.

Fast is better. When injecting Roadware 10 Minute Concrete Mender into concrete, the fast gel and cure time allows you to make a full depth repair from the bottom of the crack up to the top. If the crack you are injecting has a large hidden void, Concrete Mender repairs will start to gel and plug up the void in several minutes. Injection epoxy that takes several hours to cure will sink to the bottom of your crack and pool in the base before it has a chance to cure.

Effective. Concrete Mender is a Structural Polyurethane**. It is about as hard as typical concrete with much greater tensile and bonding strength. It is super thin at 8cps with a surface tension 1/3 of water. It can to penetrate concrete cracks and surfaces. Concrete Mender does not need to be forced into cracks with high pressure pumps and extraordinary methods. Concrete Mender can easily flow into cracks and fissures with just simple manual tools and a specially designed application mixer. You can repair more cracks in less time with less waste then ever before. Repairs are structural in nature and will move with the concrete, not against it like very hard epoxies.

Easy Application. For a repair to be effective in the field, it has to be simple enough for crews to apply efficiently. Installation productivity saves money.

To start, simply drill a 3/8″ diameter hole about one inch deep into the crack at several points along the crack. Clean the crack and holes with a vacuum.* (Click here to learn how to work safely around silica dust).

Tape off the top of the crack and around the holes you just drilled with clear duct tape or Gorilla Clear Repair Tape. These tapes have a good adhesive that will stick to the surrounding concrete. Do not use packing tape or other tapes without testing them first.

Gently squeeze the handle of the gun and slowly inject Concrete Mender into the crack. Work product into several holes at a time, moving the cartridge back and forth among them. Allow time for the Concrete Mender to start gelling in the bottom of the crack. As the crack starts to fill completely, you will see Concrete Mender flow under the clear tape from one drilled hole to the other. You may see air bubbling up from one hole as you inject Concrete Mender into adjacent holes.

Once the crack is filled to refusal, move on to the next few drilled holes until the whole crack is filled.

After 10 minutes at 70 degrees or 23 C, pull the tape. You can use a razor scraper, grinder or polishing device to remove and excess material and blend in the repair.

Using Roadware 10 Minute Concrete Mender and Soft-tip injection mixers, you can structurally repair concrete cracks and delaminations with simple tools and methods. This unique system saves time and money and allow for a high production rate for installers. The drill hole/inject method is much less invasive than traditional cut and fill methods and creates a lot less silica dust on the jobsite. The Microdoweling properties of Concrete Mender and Soft-tip Injection promises to be a winning combination for tough concrete repair challenges.

These materials and tasks are common on construction jobs. Breathing that dust can lead to serious, often fatal illnesses.” The Center for Construction Research and Training.

** Structural Polyurethane: A polyurethane based material that restores structural integrity and aggregate interlock to distressed concrete by using low surface tension and low viscosity to penetrate concrete surfaces and cross-linking polymer chains to bond directly to the concrete-aggregate matrix. This bonding action utilizes capillary forces to self-inject polymer chains into the surrounding concrete. This material should have a modulus of elasticity less than the surrounding concrete and should not become brittle over time. This material may be combined with manufactured sand to form a PCC compatible polymer concrete that can structurally repair concrete cracks and spalls.

What do you do when your pool has cracks and spalls and it has to be open is three days? Back in 2001, the City of South Saint Paul, Minnesota had a problem with their new splash pool. Just before opening the pool for its second season, cracks and spalls were discovered in the concrete pool bottom and along corner where the floor meets the wall. The damaged was probably caused by the first Minnesota winter for this neighborhood splash pool facility. The repairs needed to be done fast. The pool was scheduled to be open in just three days. Any delay would be a disappointment for local families and political problem for the City who spent a lot of money to build this water recreation facility.

The call went out to see if anyone could come up with a solution. Roadware Incorporated, also located in the City of South Saint Paul, received a call from the Parks and Recreation Maintenance Department to see if we had any ideas. It turns out, Roadware 10 Minute Concrete Mender™ is a great product for repairing concrete pools. The cross-linked polyurethanes in Concrete Mender and very resistant to water, chlorine and other pool chemicals.

Roadware personnel were at the pool within a few hours and repairs were made using a mixture of Roadware 10 Minute Concrete Mender and manufactured sand.

Roadware Contraction Joint Spalling and Repair

Contraction or control joints are cut into new concrete to control the cracking process of the concrete as it cures. If the joints are filled within the first few months, the joint filler will split as the concrete continues to shrink and crack. Use Concrete Mender after the first year to eliminate the joint problem one and for all.
